Sunday Roundup

This week, longtime torture foe -- and longtime forced resident of the Hanoi Hilton -- John McCain jettisoned his principles in pursuit of the presidency and voted against a bill banning torture. A day later, Mitt Romney, who famously boasted that he wanted to "double Guantanamo," jettisoned the venom he'd been spewing at McCain for months and offered him his endorsement. Suddenly brothers in broken arms. Romney, who less than three weeks ago was branding McCain "dishonest" and "a liberal Democrat," now hailed him as "a true American hero" and "the next president." It's amazing how fast campaign trail slugs turn into hugs in the name of party unity -- and a prime speaking slot at the national convention. And candidates wonder why voters have grown cynical?
